The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 14 months are:

2015 02 +0.296 +0.434 +0.157 +0.015

Note that the El Nino warmth in the tropics seems to have fizzled, falling about 0.25 deg C in the last few months to near the 1979-2010 average value, which is unusual since February has been the usual time of peak tropospheric warmth in response to previous El Nino events.
